mae ling earns a weekly salary of $325 plus a 6.5% commission on sales at a gift shop. how much would she make in a week if she sold $4,800 worth of merchandise

Sagot :

The weekly earning is an illustration of a linear function.

Her total earning when she sells a good worth $4800 is $637

The given parameters are:

[tex]\mathbf{Base = 325}[/tex]

[tex]\mathbf{Commission = 6.5\%}[/tex]

Let the total sales be x and the total earnings be y.

So, we have:

[tex]\mathbf{y = Base + Commission \times x}[/tex]

Substitute known values

[tex]\mathbf{y = 325 + 6.5\% \times x}[/tex]

When she sold merchandise worth $4800, it means that x = 4800

So, we have:

[tex]\mathbf{y = 325 + 6.5\% \times 4800}[/tex]

[tex]\mathbf{y = 325 + 312}[/tex]

[tex]\mathbf{y = 637}[/tex]

Hence, her total earning is $637
